If you are a Java Spring developer and working with Spring Security then you may be familiar with the "Learn Spring Security" course by Eugen Paraschiv of Baeldung. It is one of the most advanced and comprehensive courses on Spring Security and the best part of this course is that Eugen always keeps it up-to-date with the new Spring Security release. Now that version Spring Security 5 is out - he has updated his course to use new features of Spring Security 5. Btw, there is some really cool new functionality coming in Spring Security 5 for the reactive programming model, and many other improvements and new features. But, the most important one is the release of OAuth2.
